STOP-MOTION.

Y SPECIFICATION forming-part of Letters Patent No. 519,295, dated May 1, 1894.

i Application filed February 24, 1892. Serial No. l22,647. (No model.) p

To all whom it may concern:

Be it known that I, CYRUS A. TAFT, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Stop-Motions; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming` part of this specification.

' This invention has reference to improvements in stop-motions for drawing-frame coilers. Y

The object of the invention is to produc-ea stop-motion which may be secured to any drawing-frame, and which is adapted to stop the mechanism when the can is filled.

The invention consists in certain peculiar features of construction and combination of novel parts which will hereinafter be more fully described and pointed out in the claim.y

Figure 1 represents a view, partly in section, of the drawing-rolls, trumpet and reciprocatingarm,the stopping of which allows the shipper to operate and stop the machine,- together with my improved device for stopping the reciprocation of said arm, by the coiler, the liftingr of which, by the yarn or roving, operates the new stop-motion. Fig. 2 represents a top View of the same, to more clearly illustrate the construction of the new stop-motion.

Similar numbers of reference designate corresponding parts throughout.

In the drawings, 5 `indicates a bracket secured to and projecting from the drawingframe over the roving-can, to form the support and journal-bearing for the shafts 6--6, on one end of the drawing-rolls. Another bracket, like this bracket 5, is secured to the drawing-frame, to support the shafts on the other end of the drawing-rolls. The rockshaft 7 is also journaled in bearings,one supported in the bracket 5 and the other at the opposite end in a similar bracket. The rod 8 is pivotally connected with a crank on rock-shaft 7 and-is connected in the usual manner, by means of a clutch, with the driving and shipper-mechanism. On the rockshaft 7, is also secured the finger 10, which rocks with the rockshaft,-the bent end vif brating under the stop 11 of theV trumpetarm 12.

The device as so far described is the well known stop-motion for drawing-frames, operated by the sliver in passing through the trumpet.

My improvement consists in connection with the same rock-shaft 7, rocked in the same manner as has heretofore been done, and also connected exactly inthe old manner with the shi pper-mechanism, of the auxiliary linger 19, the end 2O of which rocks or oscillates beneath the end- 17 of the over-balanced lever 15. This lever 15 is supported by the auxiliary arm 13 secured to the frame and provided With the extension 14 carrying a pin on which the lever 15 is pivoted. The lever 15 is provided with a rider 16; the rider 16 rests on the liange 27 formed around the upper end of the tunnel22 carried by the coiler 23, which is operated in the usual manner to coil the cotton in the can 24. The rider 16 is made of V-shaped section, as is indicated in broken lines in Fig. 1, so that when the sliver chokes in the tunnel 22, as it is liable to do, the rider will rise' over the sliver on the flange and cause the lever 15 to rise thereby depressing the arm 17 and stop 1S. When the can has been lled,ithe continued coiling of the cotton on the top of the same raises the coiler carrying the tunnel 22, and also lifts the rider 16 of the lever 15. The arm 17, having the stop 18, Will now be depressed, and the bent end of the finger 19 coming in contact with this stop, Will arrest the rocking of the shaft 7, and the reciprocation of the rod 8. The usual shipper-mechanism and clutch 110W operate to move the belt to the loose pulley, .and thus stop the machine, exactly in the same manner as if the linger 10 had encountered the stop 11.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 4 y In a full can stop-motion fordraWing-frames, the combination with the coiler and its tunnel anda vibrating arm connected to stopping mechanism, of a. pivoted lever, a rider, connected with the forward part of the lever, said rider having inclined sides adapted to ride on the flange surrounding the inlet end of the tunnel, the rear end of the lever forming a stop adapted to engage with the vibrant-- ing arm so that the drawing-frame will be stopped automatically when the can is full and also when the sliver accumulates above the tunnel, as described. 10

In Witness whereof I have hereunto set my hand. CYRUS A. TAFT.
